Current project we started after purchasing the telerik in last year which 2018 version. Again we purchased in this /-2019, after that we download and installed the latest  product. our project smoothly and no error comes.

Yesterday I try to add one web-service of which successfully added and its added some packages. The packages shows that it is version (when I checked via  package manager- see image link attached), I tried to update package via update button, at that time it gives the below error.

"Error The local source 'C:\Program Files (x86)\Progress\Telerik UI for ASP.NET Core R1 2018\wrappers\aspnetcore\Binaries\AspNet.Core' doesn't exist.0"

How to resolve this?

I would like to make the splitter bend to my will. Can you give me an example on how to do this?:

• Make Size relative to the host (instead of hard-coded to 440px).  I'd like it to be .25% of the parent/host.
• Make the bar between the panes wider so its easier to resize it.
• Turn off the button that closes/opens the pane.  (I don't want this pane to go away)
• Set a minimum width on the left pane so it must be at least 100px.
• Change the color of the bar when it is select/not selected. and/or set the background color for ALL Kendo controls.

Hi, 

I am trying to find a suitable example of using a Kendo UI Grid to display data from a

 (v 2.0.1.0)

I can already successfully render to a native html <table> without problem so I know I have no errors in fetching and displaying data without Kendo Grid.

I have tried so far - without success :

1) http://demos.telerik.com/aspnet-core/grid/local-data-binding

2) http://demos.telerik.com/aspnet-core/grid/remote-data-binding

When the page loads I see no client-side js errors.  The grid is simply no rendered.

The IndexModel class serves as the Model for the Razor Page.

It has a simple 

This sets a Public Property to expose a collection/list of a type.

So for example if I use Kendo grid with a local datasource like so:

@(Html.Kendo().Grid(Model.Practice.Practices)
              .Name("grid")
              .Columns(columns =>
              {
                  columns.Bound(c => c.Id).Width(140);
                  columns.Bound(c => c.Name).Width(190);
                  columns.Bound(c => c.PracticeAddresses[0].Address1);
                  columns.Bound(c => c.PracticeAddresses[0].Address2);
                  columns.Bound(c => c.PracticeAddresses[0].PostCode);
              })
              .HtmlAttributes(new { style = "height: 380px;" })
              .Scrollable()
              .Groupable()
              .Sortable()
          .Pageable()
          .Sortable()
          .Scrollable(scr=>scr.Height(430))
          .Filterable()
          .DataSource(dataSource => dataSource
              .Ajax()
              .PageSize(20)
              .ServerOperation(true)
          )
    )

The page shows no grid.

Thanks in advance for any suggestions...

I am new to kendo and I am in a situation where I have a kendo grid bound to a data source and I need to add a custom filter to it. 

The filter should have a dropdownlist that has distinct values from the column "Issuer".  How can I achieve this without making another server call to get distinct Issuer values. I want to bind the dropdownlist to the existing data source which already has all the data. Please suggest.

Here's my code:

$("#DivGrid").kendoGrid({
                dataSource: {
                    transport: {
                        read: {
                            url: "/DataView/GetData",
                            dataType: "json"
                        },
                        parameterMap: function (options, operation) {
                            if (operation !== "read" && options.models) {
                                return { models: kendo.stringify(options.models) };
                            }
                            else if (options) {
                                var kendoString = kendo.stringify(options);
                                return { models: kendoString };
                            }
                        }
                    },
                    pageSize: 10,
                    schema: {
                        model: {
                            tranId: "id",
                            fields: {
                                tranId: { editable: false, nullable: false },
                                issuer: { editable: false },

                                dateAdded: { editable: false, type: "date" }                            

                            }
                        }
                    }
                },
                filterable: true,
                columns: [              
                    {

                        field: "tranId",
                        title: "TranId",
                        width: "30px",
                    },
                    {
                        field: "issuer",
                        title: "Issuer",
                        width: "50px",
                    },
                    {
                        field: "dateAdded",
                        title: "Created Date",
                        format: "{0:MM-dd-yyyy hh:mm:ss}",
                        width: "40px",
                    },
                ],
                dataBound: function (e) {
                    //something
                },
                pageable: {
                    alwaysVisible: false,
                    refresh: false,
                    pageSizes: true,
                    buttonCount: 3
                },              
            });

I have a problem trying to handle server message error on client side after a read event on grid component

my grid is setting up:

 @(Html.Kendo().Grid<myModel>().GetPageableGrid(gridName)
        .Name(gridName)
        .AutoBind(true)
        .DataSource(dataSource => dataSource
            .Custom()
            .Type("aspnetmvc-ajax")
            .PageSize(10)
            .ServerPaging(true)
            .ServerSorting(true)
            .ServerFiltering(true)
            .Transport(transport => transport
                    .Read(read => read.Action("search", "test"))
                    .Destroy(e => e.Action("delete", "test"))
            )
            .Schema(schema => schema
                .Errors("Errors")
                .Model(model =>
                {
                    model.Id(p => p.modelID);
                })
            )
            .Events(events =>
            {
                events.Error("OnRequestError");
                events.RequestEnd("OnRequestEnd");
            })
        ) ....

the javascript function:

function OnRequestError(e) {
        alert(e.errors); // show 'undefined'
}

in the controller:

DataSourceResult result = new DataSourceResult
{
    Errors = new { message }
};
return new JsonResult(result);

json response look like:

{"Data":null,"Total":0,"AggregateResults":null,"Errors":{"message":"The method or operation is not implemented."}}

I cant reach errors property on OnRequestError, I tryed differents aproacches but not results yet it is alway 'undefined'

I apreciate any help.

Hey,

so what i would like to achieve is to simply add a column to the grid, which has a button in it acting as a link. However the link needs 3 parameters to be passed to the url, which i need to take from the data source. How can i achieve that?

Used to do it like this within a table:

<a class="btn btn-light border" role="button" asp-controller="X" asp-action="Create" asp-route-id="@j.Name" asp-route-jId="@j.JId" asp-route-mId="j.MId">Open</a>

Thank you!

Regards,

Peter

Hello !

I'm testing the latest version of the Grid (2019.1.220, VS 2017, asp.net core 2.2, razor pages).

I'm using the Ajax Binding, and everything is working fine when using IISExpress. When I switch to using a local instance of IIS (version 10 on a windows 10-1803), I get a 404 error in the chrome console with the following message:

Failed to load resource: the server responded with a status of 404 (Not Found) http://localhost/Index?handler=Read

I've tried the [Web Resources Troubleshooting] page, specifically the section discussing 404, and added the telerik webresource handler to my web.config as follows:

<add name="Telerik.Web.UI.WebResource" path="Telerik.Web.UI.WebResource.axd" verb="*" type="Telerik.Web.UI.WebResource"/>

the full web.config is as follow:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
      <handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
        <add name="Telerik.Web.UI.WebResource" path="Telerik.Web.UI.WebResource.axd" verb="*"    type="Telerik.Web.UI.WebResource"/>
      </handlers>
      <aspNetCore processPath="bin\IISSupport\VSIISExeLauncher.exe" arguments="-argFile IISExeLauncherArgs.txt" stdoutLogEnabled="false">
        <environmentVariables />
      </aspNetCore>
    </system.webServer>
  </location>
</configuration>

Any ideas on why I'm still getting the same error ?

Thanks !

I have a multi-step View.  In the first Partial I want to capture the id of a Patient from a Kendo Grid.  I need to retain that value into the @Model then move to the second Partial.  In this second Partial I then capture scheduling information.  No record is persisted until I have data from both Partial Views. 

Questions:

• I am able to successfully capture the data in the function (pictured) but I need that value to be persisted back to the Model.  How do I do that?
• Help me understand the script hierarchy.
